construction and reduce the expense of manufacture, and to secure quickness and accuracy, and effectiveness of operation, and to secure other desired results, las hereinafter pointed out. Y

In the accompanying drawings, Figure V1A is an end elevation of a loose leaf binder embodying my invention; Fig. 2 is a view of a portion of the binder with the covers opened so as to show the leaf holding device in different positions; Figs. 3 and 4 are sections t-aken on lines 3-3 and 4 4 respectively in Fig. 2. p

In the drawings I show a loose leaf binder having covers 1-l, and a back 2, and I show the same provided with a series of loose leaves 3. To the back 2 is attached the leaf holding structure which more especially embodies my present invention. This preferably comprises a pair of bars or rods 4, 5V

which are secured or mounted upon the back 2 for pivotal or swinging motion, as by a screw 6. Each of the bars 4, 5, is provided at its end with upright curved members 7 and 8 respectively. These members are preferably substantially semicircular in form, so that the two together form a substantial circle, which is parallel to the circle formed upon the opposite endsof said bars. These curved members 7 and 8 are adapted to lit together and to separate by thepivotal or scissor-like movementof the bars 4 and 5, which are crossed to produce a Vseparation of the ends of the bars 4 and 5. One of the bars as 5 is downwardly ofset as shown at 5a to permit the corresponding ends of both bars 4 and 5 to travel in the same relative plane, thus permitting the same circular parts 7 and 8 of the rings to be interchangeably mounted upon either end of the bars, eliminating the necessity of any `alterations thereto, which would follow if the ends of Specification of Letters Patent.

the bars traveled in different planes. This enables the loose leaves to be put into lposition inthe binder and also taken out of the same by separating the Abars 4 and 5 so as to`open the two rings formed at the opposite ends of said bars by said semi-circularmemy bers. When the leaves are in place or removed thefmembers are closed together so as to hold the remaining leaves in proper position. The members 7 and 8 are preferably made of separate pieces of metal and secured to the ends of the bars 4V and 5 in any deirable way, as for example by rivets 9- r The bars 4,` 5, are snapped closed by lu 's 10, 10, littinginto recesses, ll, 11. rIoo wi e opening or separationvof the bars is prevented by lugs 12, working in slots or recesses 13.

-It will be seen that the yarrangement is simply and easily operated involving but very few parts, and can be manufactured at very low eXpense.

It will be understood that changes and modiiications can be made'withoutdeparting from the spirit of the invention.

What I claim is:

l. A device ofthe classdescribed comprising in combination, a pair of bars both pivoted between their ends at Va common pivot, the opposite ends of each bar being separated from the corresponding end ofclosed and the holding rings formed upon Y the opposite ends of both bars being parallel to each other when in closed position.

2. A deviceof the class described comprising in combination, a pair of bars both pivoted between their ends at a common pivot,.the opposite ends of thebars being bent so as to diverge from one another at their ends when in closed position, one part of an openable leaf holding member mounted upon each end of each bar and forming a pair of substantial rings when closed, the holding rings formed upon the ends of the bars being parallel to each other when closed, and means for limiting the movement of the bars in one direction.

3. A device of the class described comprising in combination, a pair of bars pivoted between their ends at a common pivot, the opposite ends of each bar being nor- I -mally4-V separated .from`l the y corresponding ends oftheotherbar When in closed posi- "tion,'i the vcorresponding ends of bothebars being Vmovable in the same plane, and coacting lea holdingmembers mounted upon the, ends ofthe bars.V .Y

4.- .A device Y of" the class described comprisingin combination, a pair of bars piv-v oted between their ends at a common pivot,

each end ofeach bar being provided with one part of an openable leaf holding means, andf'the corresponding ends of both bars being` movable in the same plane when the openable 'leaffholding members are operated to open'or close said means. y Y 5. device of the class specified comprising incombination, a pair of. bars pivoted together betvveentheir ends, one of said are separate frolnthe bars and secured toV l the ends of the same, said members having theirflovver ends provided vvith lateral eX- tensions'v which are secured to the bent end portionsr of the` bars.

f 6. A .device of the class described in combination', a pair of coperating pvoted bars of Auniform Width throughouttheir length, the free'ends of both bars being provided with one partof a filing device, the ends of `of uniform Widththroughout `their length, the free endsv of .both bars being provided with one part of a iiling device, both ends of said bars` which carry the filing devices f being laterally oimisetand stantially the same plane.
